I'm really not clued up on this but my understanding is as follows:

Looking at the table on wikipedia: http://en.wikipedia.org/wiki/Intel_Core_i7, it would appear that QPI is a thing of the past.

The Sandy Bridge architecture released this year does not have QPI and (hence?) only 2 memory channels and not 3.
The disadvantages of the older Intel motherboards with 1366 socket is that they do not support usb3 and SATA6 and the CPUs are more power hungry. The advantages are the 3 channel ram and other benefits of QPI such as 2 16xPCIE slots.
It seems the choice is between 2600 (Sandy Bridge) and a 930 (Bloomfield). The answer may be obvious to some but it's not obvious to me yet.

Can anyone provide some insight/discussion here? Also, has anyone here bought from Sybaritic? They look good at first glance.
